Characterizing the short-latency evoked response to intracortical microstimulation across a multi-electrode array. [PDF]
J Neural Eng, 2022 Objective. Persons with tetraplegia can use brain-machine interfaces to make visually guided reaches with robotic arms. Without somatosensory feedback, these movements will likely be slow and imprecise, like those of persons who retain movement but have ...

Differential Effects of Open- and Closed-Loop Intracortical Microstimulation on Firing Patterns of Neurons in Distant Cortical Areas. [PDF]
Cereb Cortex, 2020 Intracortical microstimulation can be used successfully to modulate neuronal activity. Activity-dependent stimulation (ADS), in which action potentials recorded extracellularly from a single neuron are used to trigger stimulation at another cortical ...

Phase-Specific Microstimulation Differentially Modulates Beta Oscillations and Affects Behavior
Cell Reports, 2020 Summary: It is widely accepted that Beta-band oscillations play a role in sensorimotor behavior. To further explore this role, we developed a hybrid platform to combine neural operant conditioning and phase-specific intracortical microstimulation (ICMS).

Bioelectronic Medicine, 2022 Background Acquired brain injuries, such as stroke, are a major cause of long-term disability worldwide. Intracortical microstimulation (ICMS) can be used successfully to assist in guiding appropriate connections to restore lost sensorimotor integration.

Forelimb movements evoked by optogenetic stimulation of the macaque motor cortex
Nature Communications, 2020 Non-human primates are useful models for understanding the human brain but application of optogenetics to non-human primates is challenging. The authors used optogenetic intracortical microstimulation in the primary motor cortex of macaques to elicit ...

Brain Stimulation, 2022 Background: Intracortical microstimulation (ICMS) of somatosensory cortex can partially restore the sense of touch. Though ICMS bypasses much of the neuraxis, prior studies have found that conscious detection of touch elicited by ICMS lags behind the ...

Visual percepts evoked with an intracortical 96-channel microelectrode array inserted in human occipital cortex [PDF]
, 2021 BACKGROUND. A long-held goal of vision therapy is to transfer information directly to the visual cortex of blind individuals, thereby restoring a rudimentary form of sight.

Perception of microstimulation frequency in human somatosensory cortex
eLife, 2021 Microstimulation in the somatosensory cortex can evoke artificial tactile percepts and can be incorporated into bidirectional brain–computer interfaces (BCIs) to restore function after injury or disease.
